1. This tiny sensor-less three-phase brushless DC motor drive module is capable of operating at a broad voltage and is made with high-quality chips. 2. When reverse polarity is reversed, the power input's reverse polarity protection feature prevents it from burning. It is ideal for do-it-yourselfers. 3. Featuring an LED indicator light to show operational status, consistent performance, and extended lifespan 4. It is a compact brushless inverter with a three-phase, three-wire drive, a three-phase, four-wire small brushless motor, sinusoidal, bass, and a small, multipurpose design. 5. supplied with a 5-PIN cable and packaged in separate electrostatic bags. Product details: DC is the working voltage. 5V to 15V Continuous working current: 1.5A Peak: 2A 15W is the maximum control power. 0.005A is the quiescent current (standby). Duty cycle of PWM: 1%–100% Measures to take: 1. The power source is
